EYEG LASSES.

SPECIFICATION forming part of Letters Patent NO. 658,748, dated October 2, 1900. Application filed July 24, 1900. Serial No. 24,716. (No model.)

To all wh0m it may concern:

Be it known that 1, CHARLES S. APPLE, a citizen of the United States, residing at Indiana, in the county of Indiana and State of Pennsylvania, have invented new and useful Improvements in Eyeglasses, of which the following is a specification.

My invention relates to improvements in eyeglasses, the object being to provide improved means for securing the spring and nose-guard to the frame or mounting of the eyeglasses, whereby secure attachment of these parts will be insured.

The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings,which form a part of thisspecification, and its novel features will be defined inthe appended claims.

In the drawings, Figure lis an elevation of a pair of eyeglasses with my invention applied thereto. Fig. 2 is a section on'the line 2 2 of Fig. 1, and Fig. 3 is an elevation of the securing-nut which holds the parts in their assembled position. Y

The reference-numerals 1 and 2 designate the lenses, 3 the spring, and 1 and 5 the noseguards. The frames or mountings each consist of a curved plate 6, conforming to the rounded edge of the lenses, the stem 7, projecting inwardly from the plate 6, and the perforated ears 8, projecting outward from the plate 6 to embrace the lens, to which the frame is secured by a rivet 9, as clearly shown in Fig. 2.

The inner end of the stem 7 is formed with parallel ears 10 and 11, which serve as a socket to receive the spring and nose-guard. Projecting centrally between the ears 10 and 11 from the inner end of the stem 7 is a pin 12, preferably formed integral with the frame or mounting or secured rigidly thereto. The pin 12 projects beyond the ears l0 and 11 and is screw-threaded to receive a nut 13 after the spring and nose-guard have been secured in place.

The ends of the spring 3 and the upper ends of the nose-guards 4 and 5 are formed with openings, through which the pin 12 extends, and after the parts have been assembled, as shown in Fig.2, the nut 13 is screwed down upon the pin 12 to clamp the nose-guard and spring firmly against the frame or mounting, after which the projecting end of the pin 12 is smoothed or'dressed by means of a suitable implement, which spreads the end of the pin, firmly locking the nut thereon.

In addition to the durability and security of the fastening device thus described the improved construction of frame or mounting permits the spring and nose'guards to be quickly attached to the mounting, as it is not necessary to carefully register the openings in the spring and nose-guards with those in the mountings, as is the case where these parts are held together by a screw.

I claim 1. An eyeglass frame or mounting having a projecting pin adapted to extend through, and secure the spring and nose-guard, and threaded at its free end, in combination with a lock-nut.

2. A pair of eyeglasses comprising frames or mountings secured to the lenses and formed at their inner ends with integral projecting pins; a spring formed at its end with openings through which said pins extend; noseguards formed at their upper ends with openings to receive said pins; securing-nuts fitting upon the projecting ends of said pins, and means for holding said nuts in position.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES S. APPLE.
